NAME
velveth_long - simple hashing program (LONGSEQUENCES)
DESCRIPTION
velveth - simple hashing program Version 1.2.09
OPTIONS
-strand_specific
: for strand specific transcriptome sequencing data (default: off)
-reuse_Sequences
: reuse Sequences file (or link) already in directory (no need to provide original filenames in
this case (default: off)
-reuse_binary
: reuse binary sequences file (or link) already in directory (no need to provide original
filenames in this case (default: off)
-noHash
: simply prepare Sequences file, do not hash reads or prepare Roadmaps file (default: off)
-create_binary
: create binary CnyUnifiedSeq file (default: off)
Synopsis:
- Short single end reads:
velveth Assem 29 -short -fastq s_1_sequence.txt
- Paired-end short reads (remember to interleave paired reads):
velveth Assem 31 -shortPaired -fasta interleaved.fna
- Paired-end short reads (using separate files for the paired reads)
velveth Assem 31 -shortPaired -fasta -separate left.fa right.fa
- Two channels and some long reads:
velveth Assem 43 -short -fastq unmapped.fna -longPaired -fasta SangerReads.fasta
- Three channels:
velveth Assem 35 -shortPaired -fasta pe_lib1.fasta -shortPaired2 pe_lib2.fasta -short3 se_lib1.fa
Output:
directory/Roadmaps directory/Sequences
[Both files are picked up by graph, so please leave them there]

Usage: ./velveth directory hash_length {[-file_format][-read_type][-separate|-interleaved] filename1
[filename2 ...]} {...} [options]
directory
: directory name for output files
hash_length
: EITHER an odd integer (if even, it will be decremented) <= 31 (if above, will be reduced) : OR:
m,M,s where m and M are odd integers (if not, they will be decremented) with m < M <= 31 (if
above, will be reduced)
and s is a step (even number). Velvet will then hash from k=m to k=M with a step of s
filename
: path to sequence file or - for standard input
File format options:
-fasta -fastq -raw -fasta.gz -fastq.gz -raw.gz -sam -bam -fmtAuto
(Note: -fmtAuto will detect fasta or fastq, and will try the following programs for decompression
: gunzip, pbunzip2, bunzip2
File layout options for paired reads (only for fasta and fastq formats):
-interleaved
: File contains paired reads interleaved in the one file (default)
-separate
: Read 2 separate files for paired reads
Read type options:
-short -shortPaired
-short2 -shortPaired2
-long -longPaired
